Detailed description

  1. Right-endpoint estimate. y = f(x) where f(x) = x squared + 1, parabola, 5 equal width rectangles between x = 0 and x = 5, with height of each rectangle determined by right value of x starting at x = 1.
  2. Midpoint estimate. y = f(x) where f(x) = x squared + 1, parabola, 5 equal width rectangles between x = 0 and x = 5, with height of each rectangle determined by middle value value of x starting at x = 1/2.
